Transform Coordinates
Remarks
Replaces Amersfoort to ETRS89 (3) (CT code 15739). Replaced by Amersfoort to ETRS89-NLD [AGRS2010] (8) in 2020 (CT code 9281). Dutch sources also quote an equivalent transformation using the Molodenski-Badekas method (CT code 4831).
Frequently Asked Questions
How do I convert Amersfoort to ETRS89 coordinates?
Use the coordinate transformation tool above to convert Amersfoort (EPSG:4289) to ETRS89 (EPSG:4258). Enter your source coordinates and click Transform. This uses the Coordinate Frame rotation (geog2D domain) method with 0.5m accuracy.
How do I transform Amersfoort to ETRS89 using Proj4js?
Use proj4.defs to define both EPSG:4289 and EPSG:4258, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Amersfoort to ETRS89 transformation?
This transformation (EPSG:4830) has an accuracy of 0.5m using the Coordinate Frame rotation (geog2D domain) method. Area of use: Netherlands - onshore.
